GAS-STOVE.

Specification of Letters Patent.

Patented Dec. 1'7, 1918.

Application filed May 23, 1918. Serial No. 236,255.

1 b all whom. it may concern Be it known that I, Gnorcn E. THOMPSON, a citizen of the United States of America, residing at Stockton, in the county of San Joaquin and State of California, have in vented certain new and useful Improvements in Gas-Stoves: and I do declare the following to be a clear, full, and exact descrip tion of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in stoves, particularly that type in which gas is used as a fuel. The primary object of the invention is to produce a stove having an inner and an outer radiating drum whereby all the heat from the gas burner will be radiated into the room in which the stove may be located. In order to accomplish this, it is necessary. that the device be provided with a carefully arranged air inlet means and discharge outlet from the inner drum whereby the cool air may be admitted thereto and, when heated, discharge readily therefrom.

A second object of the invention is so to construct the stove that it will be easily and cheaply assembled and adjusted for operation, since the proper assembling and adjusting is a vital consideration in producing a perfect stove of the type contemplated.

A still further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specifications and claims.

The figure of the drawings is a vertical section through my improved stove.

Referring now more particularly to the characters of reference on the drawings, I first provide a base chamber 1 preferably of cast metal having a groove 2 in its upper edge. I also provide a top 3, also preferably made of cast metal, provided with'a central orifice 4 having a removable covering grate 5.

The numeral 6 designates the primary air cup which is provided in its lower end with a threaded orifice 7 for a purpose as will appear. Extending inwardly from the upper periphery of this cup 6 are lugs 8 extend through the top 3. The upper edge of the cup 6 is provided with a groove 10, while the top 3 has a groove 11 on its under side alined with such groove 10 and a groove centrally orificed to receive bolts 9 which 12 alined with the groove 2. In assembling the device, the primary or outside heating drum or cylinder 13 is fitted into the grooves 2 and 12, while the secondary or inner heating drum or cylinder 14: is fitted into the grooves 10 and 11. The bolts 9 are then inserted through the top 3 and the lugs 8. The nuts 9 are then tightened. This draws the top 3, drum 14 and air cup 6 tightly together in an efficient manner, as is necessary points below the basechamber 1. It is also provided with a vertical air inlet pipe 17 which is threaded as at 18. On this threaded portion 18 is mounted the gas burner shell 19. Such shell has an upper orifice 19 of a slightly greater diameter than the pipe 17 so as to leave an escape slit from the shell into the base chamber 1. The size of this slit is adjusted by advancing the shell 19 along the threads 18 to bring the sides of the orifices 19 close toward or away from a beveled base flange 15 on the fitting 15. In this manner, the size of the slit between the burner and'the pipe or fitting may be increased or diminished. On the inner side of the base chamber 1, at the lower edge thereof, is an annular flange 20 forming a seat for the removable base plate 21 which is provided with orifices to fit over the pipes 16 and 17. The base plate 21 is held fitted in position by means of a wing nut 22 which fits over the threaded end 23 of the pipe 17, and engages such'plate.

It will be seen that the same nut 22, when tightened, also draws together the top 3, cylinder 13, and base chamber 1, through the medium of the flange 20 resting on the plate 21.

To insure a perfectly tight connection between the drum 14., top 3 and air cup 6, also between the cylinder 13, top 3, and base 1,

the grooves 10, 11, 2 and 12 will be partlyfilled with asbestos or some similar material. An adjustable gate 24 is arranged on the plate 21 around the pipe 17 to control the air supply in the base chamber 1.

A valved pipe 25 supplies the gas to the shell 19 into which it is removably threaded. This pipe extends through an elongated orifice 26 in the side of the base chamber 1 covered by a sliding collar 27 arranged around the pipe 25. This opening 26 is to allow of the pipe'25 being fitted into the shell 19 irrespective of the position inwhich it may be set on the pipe 17. Auxiliary air intake pipes 28 may be interposed between the outside of the basechamber 1 and the inside of theair (mp6.

In practice the burner is lighted andjthe heat from the same causes"the air cup 6 to become superheated. This causes the heated air to rise and as it rises it draws into said cup large quantities ofccol air throughthe various air inlets, Thisa'ir iscontinuous'ly s'uperheatedand passes through the drum 1% andoutthroughthe top grate-5. The-flames passingbetween-the 'druinszlil and M also cause the heat to be radiated througlrthe "drum-1.3150 the outside thereof: andthrough ;the'1-dru1n ltothe inside thereof, which latter function further heats-theair passing a -from the air cup* 6. :By i'n'e'ans of this Icon- V struction practically 'alltheiheat inthei'gas is-ra'diated from the stove into. the room in I which the stove may be located.
